A process for selectively removing minor amounts of beta-chloroacroleins and 5,6-epoxyhexene-1 from epichlorohydrin.

摘要

The invention relates to a process for selectively removing minor amounts of beta-chloroacroleins and 5,6-epoxyhexene-1 from a mixture made up predominantly of epichlorohydrin, characterized by treating said mixture with hydrogen at a temperature of between 20 DEG C and 150 DEG C in the presence of a catalyst comprising rhodium, platinum or palladium deposited on a non-acidic, refractory support, in an amount of from 0.05 to 10% by weight on the total catalyst and to epichlorohydrin whenever prepared by means of this process.
